UNITED STATES PATENT OFFICE.

ROBERT R. CROSBY AND J OSEPHUS HARRlS, OF BOSTON, MASSACHUSETTS.

IMPROVED CLOTH ES-WRINGER.

Specification forming part of Letters Patent No. 33,575, dated October 29, 1861.

To all whom it may concern:

Be it known that we, ROBERT R. CROSBY and JosEPHUs HARRIS, both of Boston, inthe county ot Suffolk and State of Massachusetts, have invented a new and useful Improvement in Machines for Drying or Expressing the Water from Clothes; and we do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, making apart of this specification.

The nature ot' our invention consistsin the device or arrangement forproducing the yielding pressure on the roll, which is movable in its bearings in that class of machines forthis purpose in which rolls are used, this being accomplished by the double lever C (in the drawings) being acted upon by the rubber spring D.

To enable others skilled in the art'to make and use our invent-ion, we will proceed to describe its construction and operation.

Figure l in the drawings represents afront elevation of a drying or expressing machine combining our improvement, and Fig. 2 a side View of the same.

B B represent two rolls placed in bearings in the upright frame-work A A. The bearings of the lower roll are permanent and it is provided with acrank and handle. Thejournals of the upper roll revolve in slots, in order that it may rise and fall to accommodate the varying thickness ot' the materials passed through. c

C is a double lever swinging upon fulcrums inserted in the upright frame and bent to such a shape that the short ends rest upon the journals of the upper roll B. The long ends,

extending vertically, unite in the horizontal piece at the top, which is embraced and acted upon by the rubber spring D.

E is a lever, embraced also by the spring D, by means of which the tension on the spring may be adjusted by elevating or depressing the same, the adjustment being retained by the pins a ct, dto., thereby producing the requisite pressure upon the upper roll.

H H are clamps for attaching the machine to the edge of the tub or vessel containing the clothes.

is a horizontal bar forming a part of the frame,the surfacebeing inclined, so that what.- ever Water may drip from the rolls may fall into the tub or vessel.

Fis a roll revolving upon one ot the rounds of the frame for facilitating the action of the rubber spring.

Touse this machine we secure it uponthe edge of the vessel containing the clothes by means of the clamps l-l H and the set-screws ee. the crank, any small portion of each article to be operated upon is introduced between them and the article is immediately drawn through and delivered on the outside comparatively dry, the expressed water falling into the vessel. As the thickness of the Inaterials passed through is constantly varying, the upper roll will rise and fall according to the thickness or quantity between the rolls, the yielding pressure being constantly maintained by the action of the lever C and the spring D.

That we claim as our invention, and desire to secure by Letters Patent, is-

The arrangement of the lever C and spring D, combined and operating substantially as set forth.
